This invention relates to a form for concrete curbing.

It is often desirable to provide a raised curbingalong one or more edgesof a conoreted surface, as, for example, the edge offa concrete roadway.Of course, there are other concreted surfaces where it would bedesirable to provide curbing, and it should be understood that concreteroadways are speciically mentioned herein simply as an illustration of awell known concrete surface commonly provided with a curbing.

In covering a surface, suchas a roadway, with concrete, it has beencustomary to cover a part of such surface and then to build up on thepart thus -constructed the required curbing. Difficulty has beenexperienced in constructing the curbing because of the fact that theform used therefor has had a tendency to shift during the pouring andtamping of the concrete. Of course, after the original concrete surfacehas fully set and the usual side form therefor removed, it has beenpossible to Vuse a curbing'form, anedge of which engagesthe ground,which will not shift during the pouring operation. However, this methodof constructing the curbing has the disadvantage of eliminating thebonding action between the concrete of the curbing and the concrete ofYthe surface, which occurs when the former is pouredv before the latterhas fully set.

The principal'object of the present invention is to provide a form forconcrete curbing which will not shift transversely during the pouringand tamping operations, and which,

therefore, permits the curbing to be poured beforel the concrete ofthesurface has fully set;

.f @Other objects and advantages, such as ease ofvapplication andlocation of the form, cheapness of manufacture,'as well as details ofconstruction, will more fully appear hereinafterfas the descriptionproceeds. 1

In carrying out Ythe invention, itis contemplate'dlto use longitudinallyextending memhers'spaced'transversely from each other a widthjequal to'the curbing width desired. @ne of these ymembers will be provided withmeansl for ,maintaining -the form against transverse displacement, whileboth of the members will be provided with means for supporting the formupon the edge of the concreted surface in the necessary horizontalplane.

An embodiment of the invention is illustrated in the accompanyingdrawing, wherein F l shows the form in perspective, and Fig. 2 shows theform applied to a concrete surface with the curbing arranged therein,said view being a' vertical section through the form, curbing andconcrete surface.

The form comprises longitudinally eX- tending side members l and 2.These members are spaced transversely of each other a distance equal tothe desired width of the curbing. The member l is of planeconfiguration, while the member1 2 is an angle, the foot 3 of which isof less width than the main part. The side member 1 is formed with avertical width greater than the vertical Width of the main part of themember 2, for a purpose which will later become apparent.

An angle member il, the bottom of which is in the same horizontal planeas the bottom of the foot 3, is secured to the outer side of the memberl. This angle member may extend the entire longitudinal length of themember l, or there may be a number of separate angle members of lesslength secured to the member 1 but longitudinally spaced therealong. Inorder to maintain the members l and 2 in their proper spacedrelationship, cross members 5 spaced longitudinally of the form havetheir opposite ends secured respectively to the members l and 2. Thesecross members are in the form of substantially U-shaped angle bars, thelegs of the U being the portions that are secured to the longitudinalmembers.` 'In order to give strength to the form as a whole, the crossmembers illustrated are in t e form of angle bars, but it should beunderstood that such members may take other forms. In the presentembodiment, the cross members 5 are secured to the membersl and 2 bywelding the same thereto, but it should be pointed out that othersecuring means are within the purview of the invention. l'

Likewise, it would seem opportune at this time to have it clearlyunderstood that ab though the form is shown as made up of sheet .metalit might equally as well be formed Vof wood or other materials.

As heretofore pointed out, it is customary to construct the curbing fora concrete surface after .a portion lo f suchsurface has been poured andsurfaced. This method .isfollowed either before the concrete of thesurface has fully set `or after it has fully set. The form of thepresent invention particularly adapted for use in the first method ofconstructing the curbing although nit ,could be used with the latter.The manner in which the form is arranged upon ,the concrete sur,- faceis clearly shown in Fig. 2. It is placed in ,position yalong .the kedgeof the surface so that .theangle ..4 rests .upontheupper edge ofv theusual side form imember .6, while lthe foot ,.3 rests upon .the .uppersurface .of the concrete. This application of the form .to the concreteshould .preferably .take place prior to the .time that the concretewillfhave become permanently and fully set. /Vhile the usual side member6 may be vprovided with a straight upper edge, it has been foundconvement, not only in .applying the. .curbing form but also inpositioning ,the side member 6, to provide such upper edge with anoutwardly and downwardly turned portion 7. When the curbing form hasbeen positioned with the angle 4 upon the upper edge .of the side member6 and the foot 3 upon the .upper surface of the concrete, the lowermostportion 8 of the member l will extend downwardly behind the side member6. This lowermost portion, when thus engaged behind the mem? ber 6together with the angle member 4, will clearly prevent transversedisplacement of the curbing form outwardly of the concrete surface orroadway, Therefore, when the concrete is poured for lthe curbing, theform will be held against shifting outwardly and will also be heldagainst shifting inwardly. The last mentioned shifting movement isprevented because of the fact that the curbing form is preferablyapplied before the concrete has permanently set, whereby theV part 8will extend downwardly between the member 6 and the main body of theconcrete. Hence the portion 8 will be held against trans? verse movementinwardly of the roadway or other surface by the restraining action ofvthe concrete. It will thus be possible to quickv ly and accuratelyarrange the form for re- 1 @giving the Concrete. .curbing in such mannerthat .the .curbing will .follows .definita meas.

'termined line along .the edge-of the roadway.

After the concrete' ofthe curbing and the Concrete. of the roadway-havebecome were manentl-y .set Qr have .Set .sufficiently to, allow theremoval ef thevform, the .Gross members 5 will prevde a convenientromasaing Suchyremeval- .Freinthe. iferesei ng description; it will beapparent that thefermaeelnprisngthe pres-- ent invention is of suchconstruction that it may be readily positioned and located in itsproperplace along the edge of the roadway, and will, at the same time,remain definitely in position during the pouring, tamping, and settingof the concrete.. Because of the fact that theform will be held againsttransverse vdisplacement by the usual side form 6 and the cOnQrete, it.will .be possible to pour .the concrete v.of Ythe curbing before the.concrete of the roadway has becomel fully and perma nent/ly set, therebyprocuring aI bonding ac-A tion therebetween so that the roadway and its.curbing wil-l :in .reality be a continuous, unitary, concrete body. l

The invention will be susceptible of .variations, modifications, andadaptationswithin the .scope of .the .appendedclaims- Having .thusdescribed .my invention, il claim: A a 'Awformy for a concretecurbingcomprising :members spaced transversely of each other a .distanceequal. to the :curbing width desired, and means on .each of said membersto support the form horizontal.ly,.the means on one of said .members.together with the member forming .an angleV .adapted v.to `engage thetop and side o'f vthe .usual side form to position the curb' form and.to hold .the same against 4transverse movement.
